The Long-bearded Honeyeater lives in the high mountains of east-central New Guinea. Long white feathers hanging from its chin and throat form a beard.
The head, neck, and upperparts are blackish brown, with a small orange patch of bare skin behind the eye. Long white feathers covering the chin and throat form a beard; the dark olive-brown underparts have grey-brown scalloping. The sexes are similar.
It is found mainly in high-mountain moss forest and woodland. It also occurs in shrubland and scrubby forest thickets within alpine grassland.
The bill is long and black, with a slight downward curve.
The legs are pale grey to pale blue-grey.
